[UPHPU] logging to a file

[Brady Mitchell]

Hey Orson,

It depends on what kind of data you are wanting to keep track of. If you 
want to log errors to a custom location take a look at 
set_error_handler() and trigger_error(). You first use 
set_error_handler() to define a function to handle the errors, then when 
you want to trigger an error in your code, use trigger_error().

Depending on the data being logged and how you plan to use it, it may be 
worthwhile to log to a database instead of a file. If it is errors that 
you need to log, that can be setup using set_error_handler().

In the example code you gave, you would probably want to use flock() to 
prevent multiple writes to the same line in the file.

HTH,

Brady
